Design is a gentrifying force in Martićeva, a district growing ever-popular with the city’s artists, writers, architects and designers. Once home to Zagreb’s automotive industry, the area has enjoyed a renaissance in recent years thanks to progressive enterprises like Blok Bar and literary club Booksa. This week-long celebration is more than just a street-party: organised by local design whizz Ira Payer (former president of the Croatian Designers’ Association and the brains behind SuperStudio 29) there’s a preponderance of exhibitions, workshops, cultural events and pop-up installations set in and around the Martićeva thoroughfare. The event’s raison d'etre is the opening of the rooftop garden atop the Wooden Skyscaper: a modernist masterpiece by Croatian architect Drago Ibler, the rooftop is only accessible to the public during the festival. A temporary bar serves wine, cocktails and craft beer, with impeccable views over the city.
